Apologies if this is the wrong place to ask this but, I’m running: AMD Ryzen AI 9 HX 370 w/ RX7700S (2nd Gen), and I’ve been hit with the whole “Fans Not Detected” error.
I believe it to be a false status error as it’s shown up for 7040 Series but, have no real recourse at this point, I think?
I’ve swapped my RX7700S out for the Empty Expansion Bay for now and the error has gone away. I’m just wondering if there’s been any mention of an update, like the 4.03, that fixes it? Something applicable for the 300 Series?
I’ve had this issue right after upgrading the motherboard to the HX 370. The very first boot was normal, but all subsequent attempts showed a “fan not detected” warning, and the cpu clocks were limited to ~0.5Ghz (probably a hard limit of a few watts for the CPU).
I tried multiple time reconnecting everything, swapping back from the RTX 5070 module to the 7700S or the empty expansion bay, using a different interposer, with no changes.
My motherboard (batch 1) was shipped with BIOS 3.00. I proceeded to do a BIOS update to 3.04 (from LFKN6.03.00 to LFKN6.03.04) and, after a reboot, the fan warning was gone and the clock speed was back to normal.
I haven’t had the issue since then. Either it was a bug in the 3.00 BIOS, or updating the BIOS did reset some settings I was not able to see…
I have the same issue on my FW16 AI 350 with BIOS version 3.04.
After a lot of back and forth with the support, they send me a replacement mainboard. However, this did not solve the fan detection error for me, this is getting frustrating.
Anyway, I’d be happy if you could keep us updated on the debugging progress.
I went some time with my RX7700S (2nd Gen) removed, finding that the “fan not detected” issue went away. Having just reinstalled the dGPU, the error has gone. I’m wondering if it’s less about the Motherboard and maybe more about the dGPU?
It’s strange. I was able to avoid the “fan not detected” issue by switching back to the base version of the Framework 16 laptop (empty shell, no dGPU). I stuck with that for just over a week, then now swapped back.
I didn’t get a “fan not detected” alert but an “interpose door not closed” error. After making sure it was properly closed, it booted with no problem. dGPU access, and everything.
I’ll keep an eye on it the next couple of days. If any more errors turn up, I’ll reach out to support.
Is there any way I could monitor the fans? Or power to the fans, or do you have any suggestions for what I should be on the lookout for? At least until things flare back up again (which it might, as there’s been no real change to software).
Edit: For context (AMD Ryzen AI 9 HX 370 w/ RX7700S (2nd Gen), BIOS 3.04).
Thanks for the update! I don’t have a dGPU, so I sadly can’t test that.
Now, I even got a full laptop replacement by support, and the error still shows up. So I’m really starting to suspect that this is a bios problem and not a hardware problem.
Interesting that you see an impact depending on what is in the bay. For me, at least reseating the fans does essentially nothing. But then, the fans were always detected in the BIOS menu, they were always spinning under load for me. It’s just this empty error.
I opened a Github issue, you could comment there with a summary of your issues/fixes to bump the priority a bit:
We’re having the same problems with our recent Framework 16 AI 300 series laptops w/Radeon dGPUs. Luckily working through an EC reset (hold the power button down for 30+ seconds) seems to take care of the issue. Not sure for how long, though. Seems to be a Firmware bug?
Yes, there are multiple options: In Windows, “System Monitor” should be able to do this. In Linux there are multiple options, but I use “GrellM”. Your fans should kick in at around 50C and ramp up as if temperature rises.
It’s interesting. There’s been a few different instances of it happening but with differing ways it’s been resolved. Some, elsewhere on Github, have mentioned cleaning, reinstalling interposer and reinstalled battery. Then of course here we have EC reset. Others believing maybe it’s a RAM issue.
I’m running my Framework with Crucial DDR5 RAM (2x16GB) 5600MHz SODIMM.
I don’t believe it’s explicitly “supported.” but, I haven’t exactly ran into any other obstacles or issues thus far.
Unfortunately I’ve been seeing the same problem twice now with my “AMD Ryzen™ AI 300 Series” framework 16.
Once I just removed the GPU module and re-installed it.. that helped.
Today I was seeing the problem again.. the EC reset didn’t help. What helped was just closing the laptop and pressing the GPU module a bit with my fingers (did not unscrew anything). It seems like the connection - even though all screws are tight - can get bad…
My suspicion is that because the laptop is effectively standing on its GPU module (the rubber line is connected to the GPU module), when you e.g. pick it up or pull it a bit over the table the connection can get interrupted.
